Safe Multisig API

healthy 3,134 Subscribers

Inspect any Safe (formerly Gnosis Safe) multisig smart wallet, keyless. For any Safe address on any supported chain it returns the multisig configuration — the owner signers, the signature threshold (the M-of-N), the current nonce, the enabled modules, guard and contract version — and the Safe token balances (native + ERC-20, with symbols and amounts). The multisig-inspection layer for DAO treasuries, security, due-diligence, wallet and dashboard tooling. Live, nothing stored. Backed by the open Safe Transaction Service.

Crypto Phishing Check API — oanor API marketplace

Crypto Phishing Check API

Tell whether a domain is a known crypto phishing or scam site before a wallet or user connects to it — using MetaMask's canonical eth-phishing-detect blocklist, the same list that protects millions of MetaMask users, read keyless and live. It runs the real detection logic: an exact and subdomain match against the blocklist and allowlist, plus a Levenshtein fuzzy match against high-value lookalike targets to catch typosquats like "myetherwaliet.com" or "app-wallet-uniswap.org". Check a domain or URL for a verdict (blocked, allowed, fuzzy or unknown) with the reason, search the 190,000-entry blocklist, or read its stats. The dApp-connection safety layer every wallet, browser extension, Telegram bot and security tool needs to warn users before they sign. Live, lightly cached.

Token List API — oanor API marketplace

Token List API

A live ERC-20 token metadata directory aggregated from the curated, on-chain token lists that wallets and dApps actually trust — Uniswap Labs Default, CoinGecko, 1inch, Aave and the Optimism Superchain list — read keyless from their public endpoints. Resolve any token contract address on any chain to its canonical name, symbol, decimals and logo; list a curated set in full (paged, filterable by chain); search across every list by symbol or name; and discover a token's bridged addresses on other chains. The metadata layer every wallet, swap UI and portfolio tracker needs before it can safely display or transact a token. Live, short cache only — nothing stored.

Token Approval Security API — oanor API marketplace

Token Approval Security API

Live audit of the token approvals (allowances) a crypto wallet has granted, and the risk of the contracts it has approved to spend its tokens — powered by the public GoPlus Security data, no key, nothing stored. Token approvals are the single most common way wallets get drained: once you approve a contract to move a token, a malicious or compromised spender can take it whenever it likes. This is the allowance-hygiene layer — the data behind tools like revoke.cash. The approvals endpoint lists every token a wallet has approved, who it approved (the spender contract), how much was approved and when, and whether that spender is flagged as malicious, trusted or unverified, together with a risk summary counting the dangerous approvals to revoke. The contract endpoint profiles a single spender contract before you approve it — its name, whether it is open-source, its creator, deploy time and risk tags. The chains endpoint lists the 40-plus supported blockchains. Catch wallet-draining allowances before they cost a user everything. This is the approval / allowance-risk cut — distinct from the token-contract-security, scam-detection and on-chain APIs in the catalogue.

Algorand (ALGO) On-Chain API — oanor API marketplace

Algorand (ALGO) On-Chain API

Live on-chain data from the Algorand blockchain (ALGO), a fast carbon-negative pure-proof-of-stake Layer 1, served straight from the public AlgoNode indexer and algod APIs — no key, nothing cached. The account endpoint returns any address's state: its ALGO balance, participation status (online/offline for staking), pending rewards, the Algorand Standard Assets (ASAs) it holds with their amounts, and how many apps it has created. The asset endpoint returns the on-chain registry entry for any ASA — its name, unit, decimals, total supply, creator and URL, so you can resolve USDC, USDt and thousands of tokens. The transactions endpoint returns the account's most recent transactions with the type, counterparty, amount, fee, round and time. The network endpoint returns the live chain state: the last round, the round time, and the total and online ALGO supply. Everything is read live from AlgoNode, nothing stored. This is the Algorand on-chain layer for any wallet, explorer, payments, DeFi or analytics app. Distinct from the XRP Ledger, Stellar, TRON, Aptos, EVM and Solana on-chain APIs and from price feeds — this is Algorand account state, ASA holdings, asset registry, transactions and ledger health. 4 endpoints, no key on our side.
